Z86E3116SSC Equivalent & Substitute Parts

Part Overview

The Z86E3116SSC is an 8-bit microcontroller from Zilog's Z8® series, featuring 2KB OTP program memory, 125 x 8 bytes of RAM, and 24 I/O pins. Designed for embedded applications requiring low-cost, compact control solutions, this device operates at 16MHz with an internal oscillator and integrated peripherals including Power-On Reset (POR) and Watchdog Timer (WDT).

The Z86E3116SSC is classified as obsolete. Locating equivalent or substitute components becomes necessary for ongoing production support, maintenance applications, or when original inventory becomes unavailable. Direct substitutes maintain identical electrical and mechanical specifications while offering improved availability or compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z86E3116SSC is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: Z8 processor family
• Memory Configuration: 2KB OTP program memory and 125 x 8 RAM
• Operating Frequency: 16MHz
• I/O Count: 24 pins
• Supply Voltage Range: 4.6V ~ 5.5V
• Package Type: 28-SOIC form factor
• Peripheral Set: POR and WDT functionality

Parts meeting all these criteria are classified as direct substitutes. Packaging variations (tube vs. other formats) do not affect electrical compatibility but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

The Z86E3116SSG is a direct electrical and mechanical equivalent to the Z86E3116SSC. Both devices share identical core specifications, memory architecture, I/O configuration, and operating parameters.

The primary distinction lies in product status and compliance certification. The Z86E3116SSC is obsolete, while the Z86E3116SSG maintains active production status. The Z86E3116SSG achieves ROHS3 compliance, whereas the Z86E3116SSC is non-compliant. For applications subject to RoHS regulations or requiring long-term component availability, the Z86E3116SSG is the appropriate selection.

Moisture sensitivity differs between the two parts: the Z86E3116SSC carries MSL 1 (unlimited shelf life), while the Z86E3116SSG carries MSL 3 (168-hour floor life limit). Storage and handling procedures must account for this difference.

Frequently Asked Questions (FAQ)

Q: Can Z86E3116SSG replace Z86E3116SSC in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same Z8 processor core, 16MHz clock speed, 2KB OTP memory, 125 x 8 RAM, 24 I/O pins, and 28-SOIC package. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance. Z86E3116SSC is obsolete; Z86E3116SSG is active production. Z86E3116SSG meets ROHS3 compliance standards. Moisture sensitivity levels differ: MSL 1 versus MSL 3.

Q: Does packaging format affect compatibility?

A: Packaging format (tube vs. other formats) does not affect electrical or mechanical compatibility. Both parts use the 28-SOIC form factor. Packaging differences impact procurement, storage, and handling procedures only.

Q: Are there any supply voltage or operating temperature differences?

A: No. Both parts operate across the identical 4.6V to 5.5V supply range and 0°C to 70°C temperature range.

Q: What does MSL 3 (168 Hours) mean for the Z86E3116SSG?

A: MSL 3 indicates the component must be used within 168 hours of exposure to ambient conditions after packaging removal. Proper storage in moisture-controlled environments is required. MSL 1 components have unlimited shelf life.

Q: Are both parts suitable for new designs?

A: Z86E3116SSG is recommended for new designs due to active production status and ROHS3 compliance. Z86E3116SSC is obsolete and should be used only for legacy system maintenance or replacement applications.
